Fix STOP: 0×00000050 Blue Screen Error In Windows 7

Advertisements

Microsoft has released an hotfix for fixing BSOD STOP error message seen in Windows 7 and Windows Server 2008 R2. The issue has been found in PCs having third-party application installed that uses the Windows Filtering Platform (WFP) callout driver.

The error message displayed in Blue Screen of Death (BSOD) is

STOP: 0×00000050 (parameter1, parameter2, parameter3, parameter4)

PAGE_FAULT_IN_NONPAGED_AREA

The four Parameter values will defer depending upon your system configuration.

According to Microsoft Support Service, this problem occurs:

because of an error in the TCPIP.sys system driver. When the WFP callout driver calls the “FwpsReleaseClassifyHandle0″ function to free up some system resources, the stop error occurs.
